Abstract

Proses produksi minyak bumi pada perusahaan “A” menghasilkan emisi dari unit produksi yang dapat mengakibatkan dampak lingkungan. Emisi terbesar dari proses produksi minyak bumi ini didominasi oleh gas nitrogen oksida (NOx) yang menyumbang 60% dari total emisi. Emisi dari gas tersebut berpotensi untuk mengakibatkan terjadinya hujan asam jika terlalu banyak terakumulasi di udara. Hasil emisi tersebut perlu dikontrol dan perlu adanya alternatif guna menurunkan tingkat emisi yang dihasilkan dari proses produksi tersebut.

Dalam penelitian ini dilakukan kajian dampak yang terjadi dari kegiatan produksi minyak bumi dengan menggunakan metode Life Cycle Assessment (LCA). Penelitian ini menggunakan aplikasi SimaPro 9. Dalam penilaian midpoint digunakan metode CML-IA Baseline. Unit Fungsional yang digunakan adalah per 1000 TOE (Ton of Oil Equivalent). Penilaian dampak dilakukan dengan menggunakan penilaian midpoint meliputi global warming, human toxicity, photochemichal oxidation, ozone layer depletion, acidification, eutrophication, abiotic depletion, dan abiotic depletion (fossil fuel). Lingkup analisis yang digunakan dari sistem proses adalah cradle to gate.

Hasil dari analisis menghasilkan nilai dampak paling besar berasal dari unit power generator di Field A. Kategori dampak paling besar adalah acidification dengan nilai dampak sebesar 1561501 kg SO2 eq/1000 TOE. Hasil dari analisis sensitivity check menghasilkan nilai 16% dari kedua variasi sehingga menandakan bahwa bila dilakukan program alternatif maka akan berdampak signifikan pada hotspot yang telah ditentukan. Skenario program alternatif yang direkomendasikan adalah teknologi kogenerasi dan non selective catalytic reduction (NSCR) dikarenakan dapat menurunkan acidification sebesar 69,81 %, eutrophication 69,82% dan human toxicity 69,40%.

The petroleum production process at company “A” produces emissions from the production unit that can cause environmental impacts. The largest emission from this petroleum production process is dominated by nitrogen oxides (NOx) which comprise 60% of the total emissions. Emissions from these gases are likely to cause acid rain if too much accumulates in the air. The results of these emissions need to be controlled and an alternative is needed to reduce the emissions generated from the production process.
In this research, a study of the impacts that occur from petroleum production activities is carried out using the Life Cycle Assessment (LCA) method. This study uses the SimaPro 9 application. In the midpoint assessment, the CML-IA Baseline method is used. The functional unit used is per 1000 TOE (Ton of Oil Equivalent). The impact assessment is carried out using a midpoint assessment including global warming, human toxicity, photochemical oxidation, ozone layer depletion, acidification, eutrophication, abiotic depletion, and abiotic depletion (fossil fuel). The scope of analysis used from the processing system is cradle to gate.
The results of the analysis show that the greatest impact value comes from the power generator unit in Field A. The category of the greatest impact is acidification with an impact value of 1561501 kg SO2 eq/1000 TOE. The results of the sensitivity check analysis to yield a value of 16% from the two variations, indicating that if an alternative program is carried out, it will have a significant impact on the hotspots that have been determined. The recommended alternative program scenarios are cogeneration technology and non-selective catalytic reduction (NSCR) because they can reduce acidification by 69.81%, eutrophication 69.82%, and human toxicity 69.40%.
